If you knew you were going to die in 30 seconds, do you honestly believe you lived your life without regret, resentment, fear, anger, etc...

Dying is an awakening experience to many, it's why people turn to god in their final moments. Eyes are opened in that way so we may let go of these things, forgive ourselves and others for our mistakes, you can't be blamed for saying something blue is red when you are blind, if sight was given you would see the foolishness of your actions and be humbled.
